Abstract
A cartridge for securing anchor members in a borehole in a hard receiving material holds separated components of a hardenable mass. The cartridge is formed of an axially extending outer casing enclosing an inner casing forming separate compartments within the outer casing. A first hardenable mass component is contained within the outer casing about the inner casing which holds a second component. In addition, filler material can be included in one of the components. An axially extending jacket of a foam material laterally encloses the outer casing. The jacket fills the space in a borehole between the outer casing and the borehole wall. The outer surface of the jacket has axially extending grooves for the outflow of water when the cartridge and jacket is inserted into a borehole. Further, the jacket serves to temporarily hold the cartridge in a borehole.
